[tutorials/axon] - Sample app fails to start

[krmahadevan]

When trying to start the spring boot app available in tutorials/axon, I see the below exception

11:59:14.005 [main] ERROR o.s.boot.SpringApplication - Application run failed
org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'entityManagerFactory': Requested bean is currently in creation: Is there an unresolvable circular reference?

I am a bit new to spring and so am not able to figure out what is causing the error.

ping @eugenp

Bumping the version here to

<axon.version>4.5.11</axon.version>

Fixed the problem. But I still am not quite sure as to what caused the problem in the first place and where was the circular reference.

Hi @krmahadevan , Thanks for the heads up. We'll take a look into this and fix our module.

This is resolved. Closing now.
